Nordyne: iQ Drive® Technology Air Conditioner

Nordyne sources say the iQ Drive® technology from Maytag delivers high efficiency, 23-SEER cooling in a split-system air conditioner. Conventional air conditioners cycle on and off at full capacity to maintain the indoor temperature, unlike iQ Drive which is an inverter-driven rotary compressor that provides fully variable operation. It reacts to the cooling demand and changes the system capacity by modulating the speed of the compressor motors.
